Abstract: The present invention relates to compositions comprising at least one fluoroolefin and an effective amount of stabilizer that may be a terpene, terpenoid or fullerene; or a mixture of a terpene, terpenoid or fullerene with other stabilizers. The stabilized compositions may be useful in cooling apparatus, such as refrigeration, air-conditioning, chillers, and heat pumps, as well as in applications as foam blowing agents, solvents, aerosol propellants, fire extinguishants, and sterilants.

Abstract: Provided is a composition comprising (a) at least one halogenated compound selected from the group consisting of C3-C5 hydrofluoroolefin, CF3I, and combinations thereof, and (b) an effective stabilizing amount of a sesquiterpene selected from the group consisting of farnesol, farnesene, and mixtures thereof.

Abstract: A process for the purification of a perfluorochemical composition comprises continuously mixing the perfluorochemical composition, comprising a liquid mixture of inert perfluorochemicals (e.g., perfluoroalkanes, perfluoroethers, perfluoroaminoethers, or perfluoroalkyl tertiary amines) and isomeric fluorohydrochemicals, with a stabilization composition comprising water-miscible alkanol and an aqueous solution of base (such as potassium hydroxide) made by dissolving the base in an amount of water sufficient to dissolve or disperse the fluoride salt by-products of the subsequent reaction of the base with the fluorohydrochemicals to form fluoroolefins, the amount of the alkanol in the stabilization composition being in stoichiometric excess of the amount needed to completely convert the fluoroolefins to alkoxyvinyl ethers. The process can be utilized to purify the product mixtures resulting from fluorination methods such as direct fluorination or ECF.

Abstract: HCFC blowing agents such as 141b which are stabilized with halogen-containing inhibitors such as benzyl bromide.

Binary mixtures of 1,1,2,2,3,3-hexafluorocyclopentane either with about 27 to 35 weight percent methanol, or with about 21 to 29 weight percent ethanol are disclosed as azeotrope or azeotrope-like compositions and are particularly suited for use where solvent recovery and reuse is practiced.

Abstract: A solvent, 1,1,1-trichloroethane, is stabilized against corrosion by the addition of a non-volatile polyether or complex polyether having an average molecular weight of from about 550 to about 8500. A painting formulation is prepared using the stabilized solvent.

Abstract: Azeotropic mixture of 1,1,2-trichlorotrifluoroethane (CFC-113) with cis-1,2-dichloroethylene and n-propanol or isopropanol with or without nitromethane, the azeotropic mixtures being useful in solvent cleaning applications.One azeotrope-like "mixture contains about 88-96 weight percent 1,1,2-trichlorotrifluoroethane, about 4-10 weight percent cis-1,2-dichloroethylene and about 0.1-2.0 weight percent n-propanol and boils at about 47.degree. C. at essentially atmospheric pressure. A second azeotrope-like mixture contains about 87-97 weight percent 1,1,2-trichlorotrifluoroethane, about 2-8 weight percent cis-1,2-dichloroethylene and about 1-5 weight percent isopropanol and boils at about 45.degree. C. at essentially atmospheric pressure. A third azeotrope-like mixture contains about 88-98 weight percent 1,2,2-trichlorotrifluoroethane, about 1-7 weight percent cis-1,2-dichloroethylene, about 1-5 weight percent isopropanol and about 0.1-2.0 weight percent nitromethane.

Abstract: Stabilized compositions of 1,1,1-trichloroethane containing a mixture of two dialkoxyalkanes such as dimethoxymethane and 1,2-dimethoxyethane and at least one acid acceptor such as epoxybutane, and, if appropriate, a nitrated derivative such as nitromethane.These compositions are well suited for degreasing metals and in the drycleaning of textiles.

Abstract: Stable methylchloroform solvent compositions in combination with from about 3 to about 5 volume percent of 2-butanol and from about 1 to about 3 volume percent of 3-methyl-1-butyn-3-ol have been shown to be superior solvents for removing flux from circuit boards. Such compositions have no flash point and maintain excellent distribution of the components in the vapor and liquid sections of the defluxing apparatus.

Abstract: Process for preventing soil redeposition onto textile articles made of natural, synthetic or artificial fibers or a blend thereof, during dry cleaning operations using stabilized perchloroethylene.It is characterized in that a sufficient amount of at least one C.sub.4 to C.sub.6 alcohol, chosen from amongst those having a boiling point of between 95.degree. and 140.degree. C. and those forming, with the perchloroethylene, an azeotrope having a boiling point of between 80.degree. and 130.degree. C., is incorporated into this perchloroethylene.

Abstract: An azeotropic solvent composition comprising about 64.6 to 89.0% by weight of tetrachlorodifluoroethane, about 3.7 to 34.2% by weight of an alcohol having carbon atoms of 1 to 5 and about 1.2 to 7.3% by weight of nitroethane.

Abstract: A stabilized methylchloroform for use in vapor degreasing which is stable in the presence of metals which contains pyrazine, dimethoxypropane, an acetylenic alcohol and a nitroalkane or a methylfuran. Such combination prevents corrosion of aluminum, iron, copper and zinc and the decomposition of the solvent.

Abstract: A stabilized methylchloroform solvent useful in degreasing operations in which the alkylene oxide stabilizer component normally employed is replaced by a tricyclic or quadricyclic compound containing a fused cyclopropane ring.

Abstract: Methylchloroform formulations are stable in the presence of zinc when they contain cyclopropyl methyl carbinol in place of an epoxide as a component of the stabilizer.

Abstract: Addition of 0.2-2 weight % of 2-methyl-2,3-epoxypropanol-(1), and preferably also 0.2-2% of methyl tert-butyl ether, produces highly stabilized 1,1,1-trichloroethane.
